System and method for enabling distribution and brokering of content information

ABSTRACT

A system and method for enabling distribution and brokering of content information are described. A request to download data is transmitted to a server. Information on multiple content providers storing data obtained from the server is received. Finally, identification information for one content provider, which allowed the download of data, is transmitted to the server along with payment for the download of data.

FIELD OF THE INVENTION

The present invention relates generally to data communication and, more particularly, to a system and method for enabling distribution and brokering of content information.

BACKGROUND

Today's broadband access to networks, such as the Internet and its subset, the World Wide Web, enables fast download and storage of content files to personal computer systems.

Typically, customers access a server, for example a content provider, select a set of content files residing on the server, possibly provide payment for the download of content files, and download the content files for local consumption. However, in this embodiment, since the content provider stores all the content files, access to the content may be slow due to network congestion or other reasons.

Alternatively, customers may download a number of content files from the server and may select from the previously downloaded content files, which are encrypted or locked using one of a number of available encryption techniques. After providing payment to the content provider, customers receive a decryption tool, for example a key for decrypting the content within the content files. This embodiment provides faster access to content, because the content is already downloaded at the customers' end. However, capacity issues, such as storage and bandwidth, may prevent content providers from using the pre-download technique, even if customers would make storage capacity available for download.

An alternate solution to the pre-download approach involves the distribution of content over a wide variety of private servers. Customers can access any one of the private servers and download the respective content files stored on the private server. However, this model cannot guarantee a revenue stream for the original content provider and cannot properly protect the copyright of the downloaded content files.

SUMMARY

A system and method for enabling distribution and brokering of content information are described. A request to download data is transmitted to a server. Information on multiple content providers storing data obtained from the server is received. Finally, identification information for one content provider, which allowed the download of data, is transmitted to the server along with payment for the download of data.

Other features and advantages of the present invention will be apparent from the accompanying drawings and from the detailed description that follows.

DETAILED DESCRIPTION

According to embodiments described herein, a system and method for enabling distribution and brokering of content information are described.

In the following detailed description of embodiments of the invention, reference is made to the accompanying drawings in which like references indicate similar elements, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical, functional, and other changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.

FIG. 1A is a block diagram of one embodiment for a network architecture. Referring to FIG. 1A, the block diagram illustrates the network environment in which the present invention operates. In this conventional network architecture, a server computer system 104, for example a server operated by a content provider, is coupled to a network 100, for example a wide-area network (WAN). Wide-area network 100 includes the Internet, specifically the World Wide Web, or other proprietary networks, such as America Online™, CompuServe™, Microsoft Network™, and/or Prodigy™, each of which are well known to those of ordinary skill in the art. Wide-area network 100 may also include conventional network backbones, long-haul telephone lines, Internet service providers, various levels of network routers, and other conventional means for routing data between devices. Using conventional network protocols, server 104 may communicate through wide-area network 100 to a plurality of client computer systems 102, for example customers interested in downloading content information from server computer system 104, possibly connected through wide-area network 100 in various ways or directly connected to server 104. For example, as shown in the embodiment of FIG. 1A, client 102 is connected directly to wide-area network 100 through a digital broadband connection, or a direct or dial-up telephone connection or other network transmission line. Alternatively, client 102 may be connected to wide-area network 100 through a conventional modem pool (not shown) or other type of connection. In one embodiment, multiple clients 102 may be interconnected using the wide-area network 100 and may communicate with each other through the wide-area network 100.

Using one of a variety of network connection devices, in one embodiment, server 104 can also communicate directly with clients 102. In a particular implementation of this network configuration, a server computer 104 may operate as a web server if the World Wide Web (Web) portion of the Internet is used as wide-area network 100. Using the Hyper Text Transfer Protocol (HTTP) and the Hyper text Markup Language (HTML) across a network, web server 104 may communicate across the Web with a client 102. In this configuration, client 102 uses a client application program known as a web browser, such as the Netscape Navigator™ browser, published by America Online™, the Internet Explorer™ browser, published by Microsoft Corporation of Redmond, Wash., the user interface of America Online™, or the web browser or HTML translator of any other conventional supplier. Using such conventional browsers and the Web, client 102 may access graphical and textual data or video, audio, or tactile data provided by server 104. Conventional means exist by which client 102 may supply information to web server 104 through the network 100 and the web server 104 may return processed data to client 102.

FIG. 1B is a block diagram of one embodiment for a system for enabling distribution and brokering of content information. As illustrated in FIG. 1B, in one embodiment, a server 104, for example a web server, is coupled with several clients 102, for example web clients, through wide-area network 100, such as the Internet. As described above, server 104 and web clients 102 may be implemented as conventional computer systems.

In one embodiment, software application programs for implementing the present invention run on web server 104 and at least one web client 102. As illustrated in FIG. 1B, the software application programs include a server portion of the application software, shown as server application 114, and a client portion of the application software, shown as client application 112. In addition, in one embodiment, web server 104 has access to a server storage module 124, for example a server database, which stores and manages content information and other types of information. In one embodiment, server storage module 124 is incorporated into web server 104. Alternatively, server storage module 124 may be operated as a database system independent of, but accessible to, the web server 104 through a local area network (not shown) or other means of communication.

Referring again to FIG. 1B, client application 112 includes a display component 132, for example a browser. In addition, web client 102 has access to a client storage module 122, for example a client database, which stores and manages content information and other types of information. In one embodiment, client storage module 122 is incorporated into web client 102. Alternatively, client storage module 122 may be operated as a database system independent of, but accessible to, the web client 102 through a local area network (not shown) or other means of communication.

In one embodiment, server database 124 within server 104, for example a server operated by a content provider, stores encrypted data, for example a plurality of encrypted content files, such as audio/video content files, which can be accessed and downloaded by multiple clients 102 via network 100. In one embodiment, the content files are encrypted using one of a number of available encryption techniques.

In one embodiment, a user activates client application 112 within client 102 to transmit a request to server 104 to download encrypted data through network 100. If server 104 can accommodate the request, server application 114 accesses server database 124 and retrieves the encrypted data. Server 104 then transmits the encrypted data to client 102. Client application 102 receives and stores the encrypted data in the client database 122.

Subsequently, client application 102 transmits a request to server 104 to download a decryption tool, for example a decryption key, configured to allow access to the encrypted data. In one embodiment, client application 112 uses browser 132 to communicate with the user and to prompt the user to provide payment information for the use of the decryption tool. After it receives the payment information, client application 112 sends an electronic payment to server 104 for the use of the decryption tool. In return, server application 114 within server 104 transmits the decryption tool to client 102.

In one embodiment, if client 102 decides to become a content provider and to allow retrieval of the encrypted data from its site, client application 112 within client 102 transmits a request to server 104 to download a distribution tool, for example a distribution key, from server 104. In one embodiment, the distribution tool identifies client 102 as a content provider, which stores encrypted data obtained from server 104 and makes encrypted data available to other clients 102. Server application 114 within server 104 accesses the server database 124 to retrieve the distribution tool and transmits the distribution tool to client 102.

In one embodiment, after the distribution tool is received from server 104, client application 112 applies the distribution tool to the encrypted data stored in client database 122 and embeds the identification information into the encrypted data. In one embodiment, the distribution tool is embedded in the encrypted data as a watermark, for example a digital watermark, using one of many known types of watermarking methods. The watermark contains identification information about server 104 and the client 102 which allows retrieval of the encrypted data from its site.

In an alternate embodiment, if client 102 decides to become a content provider and subsequently downloads the distribution tool, server 104 may also store the distribution tool and its relationship with client 102 in a list of additional content providers stored within server database 124 and may provide the distribution tool to other clients 102 requesting the same encrypted data, as described in further detail below.

In one embodiment, client 102 becomes a content provider for a predetermined period of time. After the predetermined period of time, the distribution tool expires and client application 112 within client 102 needs to send a new request to server 104 to update the distribution tool and to reinstate its status as content provider.

Alternatively, client 102 may become a content provider until it transmits a request to server 104 to be removed from the list of additional content providers stored in server database 124. In this embodiment, client application 112 transmits the request and server application 114 within server 104 accesses the server database 124 and removes the client 102 from the list of additional content providers.

In another alternate embodiment, server 104 may periodically poll each client 102, which is an additional content provider, using one of many available polling methods. Server 104 may then determine the status of each polled client 102 and may remove any client 102 that requests to be removed.

In one embodiment, if server 104 is overloaded and cannot accommodate the request received from client application 112, server application 114 accesses the server database 114 and retrieves the list of additional content providers. Server application 114 transmits information on additional content providers to client 102, for example links to the additional providers which store the encrypted data obtained from server 104 and which allow retrieval of the requested encrypted data from their sites. In one embodiment, the additional content providers are also clients 102 connected to server 104 via network 100.

In one embodiment, client 102 requesting the download of encrypted data communicates with one of the additional content providers using one of the provided links. If the accessed content provider can accommodate the request, the client application 112 of client 102 downloads the encrypted data and the embedded distribution tool, which identifies the particular content provider, and stores the encrypted data in client database 122. Client application 112 then transmits a request to server 104 to download the decryption tool for decrypting the retrieved data and provides payment for the use of the decryption tool, as described in detail above.

At the same time, in one embodiment, client application 112 communicates to server 104 identification information related to the accessed content provider, for example the distribution tool identifying the content provider. After the decryption tool is transmitted to client 102, server application 114 sends a fee to the content provider, which accommodated the request and allowed the download of encrypted data. In one embodiment, the fee is predetermined and represents a percentage of the payment for the use of the decryption tool provided by client 102.

In an alternate embodiment, if server 104 cannot accommodate the request, it may provide information on additional content providers to client 102, which may include the links to the additional providers, as well as the distribution tool associated with each additional content provider. Client 102 may use the links to connect and download encrypted data from one content provider. Once the encrypted data is downloaded, client 102 may communicate the distribution tool associated with the content provider back to server 104 for proper credit of the fee.

Having briefly described one embodiment of the network environment in which the present invention operates, FIG. 2 shows one embodiment of a computer system, which illustrates an exemplary client 102 or server 104 computer system in which the features of the present invention may be implemented.
